Alberto de Agostini National Park

Alberto de Agostini National Park

To the south of the Cockburn Channel, you'll sail by Alberto de Agostini National Park. This is where the Andes, the world's longest above-ground mountain range, comes to an end in its southernmost extension, the Cordillera Darwin. Chile's third-largest park has a landscape of soaring peaks and deep fjords, though a large part of why it was added to UNESCO's list of Biosphere Reserves is harder to spot from a ship. The biosphere that includes it and nearby Cape Horn National Park is home to 5 percent of the world's bryophytes, that is, those plants without vascular systems, including mosses and liverworts.
